when i tried to define a bool type data or use bool type as my function's parameter,there is many error messages displayed in the concole.
like this:
../hello_world.c:23: error: `bool' undeclared (first use in this function)
../hello_world.c:23: error: (Each undeclared identifier is reported only once
../hello_world.c:23: error: for each function it appears in.)
../hello_world.c:23: error: syntax error before "b"
i figured that the compiler recognised bool as a valid data type since it is highlighted the same as other types.
How to fix that?
ps:i only include <stdio.h>in my program.
